Re: [Paparazzi-devel] Quad Tilt Rotor using Lisa/M

[David Conger]

Hey Mark,

Have you see this: http://www.youtube.com/watch?v=Z7XgRK7pMoU

Transitioning platform code is written and tested in Paparazzi
already. Note the landings of the winged body (Quadshot) as it nears
landing it switches to hover and lands. The wind was howling that day
(I was there)...easily 20+ MPH.

What makes Paparazzi the one to use is the maturity and depth of the
code. The real world is not still air and perfect conditions.
Paparazzi excels in real world conditions and very imperfect weather.

PixHawk, my opinion is it's new hardware and untested. That project
measures itself primarily in business terms of units made and sold not
successful flights or missions and competitions won. Granted they are
extremely successful in business terms but I have yet to see success
measured in real world missions or competitions. They are very
aggressive marketers and are very good at selling their project so I'm
not surprised you were contacted after posting here. They also have
many members subscribed to this email list.

Paparazzi is used by quite a lot of people actually. It is a very
mature, open and growing community. They are all just quietly doing
academics or research projects very much like yours not sales or
marketing. There are even several commercial platforms with Paparazzi
under the hood. A few Govt projects using Paparazzi based systems.
There are Paparazzi drones flying for more than 7 years in the Arctic
and Antarctic regions doing atmospheric research. These are not people
planning but real, complex missions like yours successfully flying.
Success in Paparazzi terms is measured in members starting, building
and flying the mission intended with 100% accuracy and zero failure.
Success is also measured in winning UAV competitions around the World.
Paparazzi since 2002 has either won or placed top three every year,
year after year. A Paparazzi based team TUDelft won the outdoor and
indoor competition for IMAV2013 by flying simultaneously 12 drones
with a single operator using a single laptop ground station (video URL
given above).

I think you have chosen Paparazzi so I'm probably preaching to the
choir. You've made a great choice. You are in good company here and
there are many in the USA and Worldwide to help you along. Welcome.

David
